10 Considerations Calling Name and Number Feature Calling Name delivery and presentation features are not supported by the Alcatel 4400 PBX. When configuring Cisco 2621 (H.323) Gateway to emulate User side (Alcatel emulate Network side), make sure that the Display IE Delivery box is T checked in CallManager H.323 Gateway Configuration, otherwise calls will not be completed. Alcatel PBX complains about the Caller ID Display information being sent in the SETUP message from CallManager by sending STATUS message with cause of IE non-existent/unimplemented. When calling from Cisco 7960 IP phone to Alcatel digital phone, Calling/Called Number is displayed on both phones after the call is answered as expected. When calling from Alcatel digital phone to Cisco 7960 IP phone, IP phone displays Connected Number after the call is answered. Alcatel phone however does T get updated when the call is answered. It displays the trunk name. It was verified using ISDN protocol analyzer that the CallManager was not sending Connected Number information in the connect message back to PBX. Page 10 of 22

As shown in the diagram above, an Alcatel 4400 PBX was connected via an ISDN E1 PRI link to a Cisco 2621 Gateway, which in turn, was connected to an Ethernet switch. The interoperability testing involved Layers 1, 2 and 3 on the ISDN PRI link between a Cisco 2621 and the PBX. Page 16 of 22

17 Layer 1 (Physical Layer) The Alcatel 4400 PBX configuration screen for the E1 trunk interface is reached using both Alcatel Board and Board\Digital Access menus, setting the E1 physical layer parameters. Layers 2 & 3 (Q.921 and Q.931) Layer 2 and 3 packet exchanges were monitored using an Acacia Clarinet protocol analyzer, bridged across the PRI link in high impedance mode. Layer 2 Q.921 packets were monitored to ensure that each PBX/2621 software configuration properly exchanged SABME/UA packets to initialize the ISDN link, and then RR packets were exchanged every 30 seconds. Layer 3 Q.931 packets were monitored to ensure that the appropriate call setup/teardown packets were exchanged for each configuration, and that the SETUP packets contained the mandatory Information Elements with the necessary details, as well as optional IEs such as Calling Name and Number. Telephone calls were made end-to-end in both directions through the Cisco 2621 Gateway, and a check was made to ensure that there was an audio path in both directions for each call. User/Network Settings The Cisco 2621 Gateway with ISDN switch type setting of primary-net5 supports both protocol sides by using the isdn protocol-emulate network/user command. The Alcatel 4400, supports both USER (slave) and NETWORK (master) protocol sides. The following options are of particular interest: Trunk interface type must be set to PRA2. Network/User options are set in the Board/Digital Access Options menu. Network mode must be set to Yes for (Master/Network) or - (Slave/User). Access Type must be set to T2. Q931 signal variant is used to determine Protocol type. This option was set to ISDN all countries.
